Sasuke Uchiha (うちはサスケ, Uchiha Sasuke) is one of the main characters in the Naruto series. Originally introduced as a protagonist as a genin-level shinobi of Konohagakure's Team 7, he later became an antagonist who is affiliated with the Akatsuki. Sasuke is currently a missing-nin, declared as an international criminal, and the sole survivor of the Uchiha clan.
When he was a child, Sasuke was very kind, loving towards his parents and older brother and respectful to his fellow clansmen as well as his teachers. He was even very proud of being Itachi's brother and Fugaku's son — famous for being devoted protectors of Konoha, and he desired to emulate them. His original dream was to join the Konoha Military Police Force when he grew up, like his father and as such greatly sought his father's approval and acknowledgement of his abilities. After Itachi massacred the clan, Sasuke's ideals and personality changed drastically and he became cold, indifferent, cruel, cynical, somewhat arrogant, and devoted the next nine years of his life to kill Itachi.
When first introduced to Team Kakashi, Sasuke displayed great indifference to his team-mates as well as others. Feeling superior to all of them, including his teacher, Sasuke was unwilling to cooperate with any of his team-mates, as he felt they would provide him no aid in furthering his ambition to kill his brother; this attitude affected his grades in the Academy after losing his clan, he had the lowest score in cooperation and second lowest in assertiveness. However over time, as he interacted more with his team mates on a day-to-day basis, he began to see them as somewhat of a family and Sasuke started to lose some of his hatred, caring more about his team than his revenge. Sasuke even admitted to Naruto that he almost thought that he must forget revenge and instead focused on Team 7. However, Orochimaru branded Sasuke with the Cursed Seal of Heaven during the Chūnin Exams to help push him back into his desire for vengeance and to give him a taste of power. Although Kakashi Hatake sealed away the Cursed Seal, and taught him the Chidori in the hopes of deviating him from the path of revenge, Sasuke began to draw more power from the seal in the hopes of getting stronger. And thus his previous ambition was renewed while causing him to disregard camaraderie once again.
According to Kakashi, Sasuke has both a superiority and an inferiority complex, as he is unwilling to acknowledge when someone is stronger than him, but obsesses when he believes that they are. For example, he was complacent with his rivalry with Naruto when he believed he was the stronger of the two, but upon noticing Naruto's fast growth, showcased in his victory over Sunagakure's jinchūriki, Gaara, who had previously beaten Sasuke, and his own quick defeat by Itachi on his return to Konoha, all culminated in his defection to Otogakure to seek power from Orochimaru.
In Part II, Sasuke became increasingly confident in his newfound abilities. Constantly, he remained composed and unconcerned with the situation at hand. Even when pressured by enemies like Orochimaru or Deidara, he showed no emotional build up; ironically, acting much like his older brother and only getting worked up when it involved Itachi. Despite getting stronger, Sasuke seemed unwilling to needlessly kill in his quest for revenge displaying that he still had some morals left. Sasuke, however, retained his habit of underestimating his opponents, shown in his overconfidence in his battles. Although, Sasuke is not above admitting his mistakes on such things, as shown after his battles with Deidara and Killer B where he acknowledged that the former was stronger than he thought and that the latter had given Taka a much harder time than he expected.
Sasuke has displayed an overbearing sense of pride in his clan's name and a great sense of loyalty to it and kept wearing his clan's crest on his back proudly while refusing to wear any other symbols such as a forehead protector. Despite claiming earlier that he did not care if he had to sacrifice his own body to Orochimaru as long as it served his quest for revenge, when Sasuke felt he had grown stronger than Orochimaru he thought that to give himself up to someone weaker than himself was insulting to the Uchiha. He also views anyone outside of the clan wielding its dōjutsu as an insult, as the eye is representative of the Uchiha clan's powers, showing disgust towards Danzō Shimura who had ten Sharingan embedded in his arm, and an eleventh one in his right eye socket and stated that Kakashi should feel grateful to the Uchiha for the power of his Mangekyō Sharingan. According to Tobi, Sasuke alone is shouldering the entire hatred of the Uchiha clan — an ideal which has been passed down for generations within the clan.
After his battle with Itachi, which concluded in the latter's death, the revelation that he had actually been ordered by the Konoha Elders to eradicate the clan coupled with the new knowledge that Itachi had truly loved him, Sasuke vowed to kill the elders for using his brother and ordering him to massacre the Uchiha clan. After he confirmed the truth, Sasuke quickly grew to loathe the village that he once called home and vowed to destroy the village, thus separating any connection it and "the rotten ninja world" had to the Uchiha clan and purify the clan's name in the process.
As time passed on with this new path of revenge and with further corruption by Tobi, Sasuke has grown much more cruel and ruthless, with the remaining morality he showed during his time with Orochimaru fading rapidly; by the time he launched an attack against the Kage Summit, he killed anyone who stood in his way, not caring about his team, and after cornering Danzō, Sasuke turned to sacrificing one who got taken hostage to accomplish his goals of vengeance, and attempted to kill his former team-mates and teacher whilst experiencing neither shame, guilt, nor remorse for any of his actions.
Initially, Sasuke still held onto the notion of sparing the innocent and teamwork, witnessed in his creation of a new group of shinobi. Though, as he became more consumed by his thirst for vengeance, he showed that he cared for them as no more than tools to achieve his hatred-fueled goals, quickly discarding them when they were no longer necessary. This is seen at the Kage Summit where he leaves Jūgo and Suigetsu behind, taking only Karin with him who could lead him to where Danzō was, as well as killing many samurai who stood in his way. He would later discard Karin as well, unhesitatingly piercing her just to kill Danzō and then attempted to finish her off to prevent her from being a burden in the future. Even when Sakura's childish crush turned into more serious affection, Sasuke still did not return the feelings, though before he left the village, he gave Sakura a genuine thank you. But would later, after that same battle with Danzō, when he had to fight with Team Kakashi, where he attempted to kill Sakura twice despite her showing obvious hesitancy to do the same. Despite his arrogance, Sasuke is not above giving praise to his enemies as he commended Gaara for the strength and speed of his absolute defence and admitted that Kakashi was very skilled at using the Sharingan for someone who wasn't an Uchiha.
After expressing a feeling of exhilaration that he had never before felt upon killing Danzō and even declaring that he sees that killing the members of Konoha as a high priority and satisfaction, Karin, Kakashi, Sakura, and the rest of Konoha 11 completely lost all hope for him. Upon receiving his "Eternal Mangekyō Sharingan", Sasuke's cruelty seemingly reached a new level when he killed White Zetsu simply to test out his new powers. He's also grown to be an impatient individual and brutal in battle. Despite Tobi's influence being one of the main sources of Sasuke's corruption and their same path of hatred and revenge, as well as believing that Tobi is a fellow Uchiha, Sasuke refused to acknowledge Tobi as his ally, and even speaks rudely to him at times. He has also shown great rage whenever someone mentions Itachi in a negative way, crushing Danzō with his Susanoo for speaking ill of his brother and ready to murder a team of ignorant Konoha shinobi for doing the same. Sasuke's hatred has also twisted any of his potentially happy memories of Konoha into negative ones in order to fuel his vengeance.
During the second day of the Fourth Shinobi World War, upon reuniting with a reincarnated Itachi, Sasuke showed a somewhat more vulnerable side to himself instead of his usual coldness. This showed just how confused and torn up he is over Itachi's decision, telling his brother that he did not understand why he was spared during the massacre and apparently implying that he would have rather died as a child than have had to deal with the grief and suffering. Having to live through many lies Itachi set for him, Sasuke wanted to hear the truth from Itachi himself.
Sasuke_ Chidori
The Chidori is Kakashi Hatake's first original technique, though he more frequently uses an S-ranked version known as the Lightning Cutter. He created it around the time he was promoted to jōnin, and later taught it to Sasuke Uchiha.
This technique channels a large amount of lightning chakra to the user's hand. The amount of chakra is so great that it becomes visible. The high concentration of electricity produces a sound reminiscent of many birds chirping, hence the name. Once the technique is completed, the user charges forward and thrusts the Chidori into the target. This produces heavy amounts of damage that is usually fatal. This technique is classified as an assassination technique because of the speed at which it is performed, despite the loud noise it produces. As shown against Killer B, Chidori can also be used to simply give the opponent a large electrical shock without impaling them.
Mangekyō Sharingan
Sasuke Uchiha awakened his Mangekyō Sharingan after learning the truth about his brother, Itachi. In his grief over the knowledge that Itachi was not the villain he imagined him to be, coupled with Sasuke's own role in Itachi's death, he awakens his Mangekyō Sharingan. Unlike other Sharingan, which have a black design and red background, Sasuke's Mangekyō is the first one that is shown to have a red design and a black background.
Sasuke has been shown using the same Mangekyō Sharingan abilities as Itachi, but in an inverted manner. With his "right Mangekyō" he can use Tsukuyomi to break a target's will and paralyse them. Danzō Shimura stated that Sasuke's version is not yet capable of altering the victim's perception of time, and thus is vastly inferior to Itachi's. With his "left Mangekyō" he can use Amaterasu. It has been implied that his skill with Amaterasu surpasses Itachi's, as he is able to apply Shape Transformation to the flames, creating the Blaze Release, and even extinguish them. Sasuke has displayed the ability to use Susanoo, which he can even partially manifest to fit the situation, such as using a ribcage for defence or manifesting only an arm to interact with his surroundings. Sasuke's Susanoo develops in stages during various battles; he first starts using an incomplete version against the Fourth Raikage, develops a version capable of firing arrows while fighting with Danzō, and later forms a version almost identical to Itachi's during his battle with Kakashi. Sasuke's Susanoo appears more demonic than Itachi's.
Due to having much larger chakra reserve than his elder brother, Sasuke can use the Mangekyō Sharingan techniques more than three times a day. While Itachi was critically exhausted after using Tsukuyomi and Amaterasu once each, and then Susanoo as a last resort technique that ultimately led to his death, Sasuke could maintain Susanoo for extended periods of time, on top of using the Amaterasu and Tsukuyomi several times a day along with some other chakra-consuming techniques like the Chidori. Regardless, like Itachi, using the Mangekyō Sharingan puts a great strain on Sasuke's body and eyes.
Initially, Sasuke refused to transplant Itachi's eyes to restore his vision even when it was reduced to a heavy blur at best, claiming that his views were different from Itachi. However after meeting Naruto again and shocked at his determination to save Sasuke from his darkness, Sasuke decided to take Itachi's eyes so he could kill Naruto with his full strength. His Eternal Mangekyō Sharingan takes the shape of his old Mangekyō Sharingan but incorporates a straightened version of Itachi's Mangekyō Sharingan design into the centre. His new eyes produce a more ghostly-shaped Susanoo. It is also able to condense Amaterasu and lock on multiple targets at once.
Shisui Uchiha acquired his Mangekyō Sharingan at some point in time through unknown means. It granted him the ability to cast powerful genjutsu techniques, the most powerful of his genjutsu arsenal being Kotoamatsukami. This technique allowed him to manipulate an opponent's thoughts without them having the slightest idea that they were being controlled. The only drawback of using that technique was the fact that it would render his Mangekyō unusable for quite some time without aide. A highly coveted ability, Shisui's right eye was stolen by Danzō Shimura while he was still alive. Shisui entrusted his left eye to Itachi Uchiha and told him to protect the village; Itachi implanted it into a crow and stored it inside Naruto Uzumaki. He then made it appear as though he had crushed his own eyes in order to prevent a feud over his eyes and erased his existence, though it was thought that he was drowned by Itachi in the Naka River. When activated, Shisui's Mangekyō Sharingan has four points which go around in a circular, saw-like motion. Both eyes are eventually destroyed, with Danzō crushing his before dying and Itachi incinerating the crow after it came back out of Naruto.
Eternal Mangekyou Sharigan
The Eternal Mangekyou Sharigan or Eien no Mangekyō Sharingan is a very powerful technique. Not only that the user will not go blind from using it, he has also unlimited access to great powers.
Sasuke got his Eternal Mangekyou Sharingan when Madara transplanted Itachi’s eyes to Sasuke. That’s how a Mangekyo Sharingan is transformed to Eternal Mangekyo Sharingan.
Sasuke can use his new Susanoo after having the eternal mangekyou sharingan. Sasuke, using his Susanoo, attacks a White zetsu clone and use Amaterasu on him. Sasuke mentioned that he can clearly see in the darkness and wants to head outside in the open to test his new eternal mangekyou sharingan.
Sasuke Uchiha_Susanoo
Susanoo, also known as the Tempestuous God of Valour (勇武の荒神, Yūbu no Aragami), is the third ability granted by the Mangekyō Sharingan after awakening the abilities in both eyes. It creates a gigantic, humanoid being that surrounds the user. As one of the strongest techniques granted to those that have acquired the Mangekyō Sharingan, it is the user's guardian deity, but at the same time, it consumes the user's life.
